TECHNICAL FIELD

The present disclosure relates to machine behavior, and more specifically a system for monitoring onboard activity and behavior classification of machines.

BACKGROUND

Large machines, such as, excavators, backhoes, front-end loaders, bulldozers, dump trucks and other such machines, may be used to carry out an assortment of earthmoving tasks. Examples of such tasks may be, digging, grading, loading, unloading and transporting materials from one location to another, however other tasks are possible. In some cases, these large machines may be used at mining sites, construction sites, road building sites, or other such job sites. Moreover, due to the complexity of the tasks and expansive size of job sites, a number of machines may be required to work together to get the job done. For example, an excavator may be used to dig a hole and a load a dump truck with the material removed from the newly created hole, while the dump truck may then transport the material and dump it at a second location. In order to reach efficiency targets and maintain a safe job site, machine operators and job site supervisors may need to monitor and analyze machine activity and behavior. Moreover, at complex job sites with multiple machines working in a single area it can be increasingly difficult for the job site supervisors to monitor and track the progress of each machine.

During normal machine operation, the operators may sit or stand at a control terminal containing the machine controls and other machine instrumentation. For example, controls such as a steering wheel, a joystick, levers and pedals may allow the operator to direct the machine to perform an assortment of tasks, however other controls may be required to operate the machine. Moreover, the operator may use other instrumentation to help control and monitor the machine, such as, image, motion, temperature, orientation sensors or any other known sensors. These sensors may provide the operator with additional machine and environmental data that, when combined with the machine controls, allow the operator to better perform certain tasks and operations. Alternatively, with the additional sensor data it may be possible for the operator to control the machine remotely from another job site location or even from an off-site location.

In order to complete tasks in an efficient manner, the additional sensor data may be used to help monitor and analyze the machine activity and behavior by equipment operators, job site supervisors or other interested individuals. For example, a machine operator may have a partially obstructed view of job site while sitting in the cab of the machine and therefore may find it advantageous to use the sensor data to help keep track of what they are doing. Alternatively, or additionally, the job site supervisor may be able to use the sensor data to determine a rate at which work is being done, how long it takes to complete a certain task and the operational status of certain equipment, however other uses are possible. In so doing, the job site supervisor may further use this data to adequately plan out resource requirements to complete a specific job. Moreover, equipment operators and job site supervisors may be able to review the data and apply the results to maximize efficiency through better planning of machine movements.

One method and apparatus for determining the loading of a bucket is described in U.S. Patent Application Publication, US 2008/0005938 to Aebischer et al., (“the '938 application”). The '938 application discloses a method for determining the load of an excavator bucket. The application more particularly relates to a method for determining the position of a load surface in an excavator bucket using a distance measuring camera and the determination of a load volume from the position of the load surface combined with the position and shape of the bucket. In order to determine the position of the bucket the method disclosed in the '938 application requires obtaining a distance measurement of at least three points along the upper bucket edge using a camera. Furthermore, in the method disclosed by the '938 application a load volume is determined by using the position of the load surface combined with the position and shape of the bucket.

Among other things, the '938 method and apparatus fail to provide a system for monitoring and analyzing machine movement and overall behavior. Furthermore, the method and apparatus disclosed in the '938 application fails to provide a solution that works with equipment from different manufacturers. These and other shortcomings of the prior art are addressed by this disclosure.

In some embodiments, the job site 22 may have a fleet 64 of machines 66, 68, 70, and 72 configured to perform tasks such as digging, hauling, dumping, moving earth, hoisting or other such operations. Moreover, the embodiment illustrated in FIG. 3 shows four machines 66, 68, 70, and 72 located at the job site 22, however fewer or greater numbers of machines may be used. Furthermore, the machines 66, 68, 70, and 72 may include similar elements as those discussed above with machine 20, however other elements may be included. In some situations, the fleet 64 may be composed of a single type of machine 20 and in other situations the fleet 64 may be composed of multiple types of machines 20 working at the job site 22. Moreover, machines 66, 68, 70, and 72 may be all sourced from a single manufacturer and have the machine behavior data collection system 52 installed as part of the manufacturing process. Alternatively, the machine behavior data collection system 52 may be installed on legacy machines that are already in use at the job site 22 or at another location. Furthermore, in some embodiments, it may be possible that machines 66, 68, 70, and 72 are sourced from one or more different manufacturers and the machine behavior data collection system 52 may be compatible with machines 66, 68, 70, and 72 from any manufacturer.

In one embodiment, the fleet 64 of machines 66, 68, 70, and 72 are each equipped with a machine behavior data collection system 52 that includes one or more imaging apparatus 42, as described above. Furthermore, machines 66, 68, 70, and 72 may each be equipped with the communication apparatus 56 coupled to the machine behavior data collection system 52, as described above. In some embodiments, each communication apparatus 56 may allow machines 66, 68, 70, and 72 to communicate and with each other over a communications network 74 set up on the job site 22. Moreover, the communications network 74 may be configured to allow machines 66, 68, 70, and 72 to send and receive data between one another.

FIG. 4 shows a schematic of a machine behavior electronic data analysis system 76 that may be configured to analyze machine behavior data 49 from the machine behavior data collection system 52 installed in machines 20, 66, 68, 70, and 72. Moreover, the machine behavior electronic data analysis system 76 may be configured to send and/or receive machine behavior data 49 or other instructions to and from machines 20, 66, 68, 70 and 72. In some embodiments, the machine behavior electronic data analysis system 76 is located on the job site 22 in the operations center 50 or at an off-site location (not shown). Additionally, or alternatively, the machine behavior electronic data analysis system 76 may be located on one or more of the machines 20, 66, 68, 70 and 72.

In some embodiments, the machine behavior electronic data analysis system 76 may include a communications apparatus 78, data analytics module 80, and an input/output terminal 82. The communications apparatus 78 may be coupled to the data analytics module 80 which is configured to send and/or receive machine behavior data 49 to machine 20, 66, 68, 70 and 72 or other piece of equipment located on the job site 22 or other location. Moreover, the communications apparatus 78 may connect the machine behavior electronic data analysis system 76 to the communications network 74 set up at the job site 22. The communication network 74 may facilitate communication between the machine behavior electronic data analysis system 76 and the machine behavior data collection system 52 installed on machines 20, 66, 68, 70 and 72 and communication may be transmitted through a satellite data network, a cellular data network, a computer data network, a Wi-Fi network, a radio frequency data network or any other known communication network.

A user of the machine behavior electronic data analysis system 76, such as an operator, a job site supervisor or other interested person, may rely upon the input/output terminal 82 to access the machine behavior electronic data analysis system 76. In some embodiments, the input/output terminal 82 may have one or more input devices (not shown) such as a keyboard, mouse, dial, button, touch screen, microphone or other known input device. Additionally, the input/output terminal 82 may have one or more output devices (not shown) such as, a monitor, speaker or other known output device. Furthermore, the input/output terminal 82 may allow the user to view data, input data, input commands, communicate with machines 20, 66, 68, 70 and 72 or perform other functions of the machine behavior electronic data analysis system 76.

In some embodiments, the data analytics module 80 is configured with a hard drive, flash drive, compact disc (CD), digital video disc (DVD) or other known storage media to store the machine behavior data 49 produced by the machine behavior electronic data analysis system 76. Furthermore, the data analytics module 80 may save data collected by the machine behavior data collection system 52. Moreover, the data analytics module 80 may be configured with software and hardware (not shown), such as a processor for performing calculations, executing functions and accessing machine information stored in a memory location.

FIG. 5 shows a diagram of an embodiment of an exemplary process flow 84 that may be used by the machine behavior classification system which is composed of the machine behavior data collection system 52 and the machine behavior electronic data analysis system 76. The process flow 84 may begin by the machine data collection system 52 sending a video data stream 86 from one or more of machines 20, 66, 68, 70 and 72. The video data stream 86 may be received by the machine behavior electronic data analysis system 76. Upon receiving the video data stream 86, the machine behavior electronic data analysis system 76 may first be configured to subtract the surrounding background 88. In some embodiments, the background subtraction 88 may be performed by software that is installed on the data analytics module 80 of the machine behavior electronic data analysis system 76. Moreover, the software may utilize an image recognition and analytics algorithm configured to detect certain machines 20, 66, 68, 70 and 72 elements, such as the tool 32, the boom 36, the arm 38 or any other machine element. The software may also be configured to retain the machine behavior data 49 related to the machine 20, 66, 68, 70 and 72 and the desired elements and subtract data of the surrounding environment and non-essential machine elements.

Following the background subtraction 88, the machine behavior electronic data analysis system 76 may make a determination whether machine 20, 66, 68, 70 and 72 is observed to be moving 90. If the machine behavior electronic data analysis system 76 determines machine 20, 66, 68, 70 and 72 is not moving 92, then machine behavior electronic data analysis system 76 may determine the machine 20, 66, 68, 70 and 72 is in an idle state 94. Moreover, if the machine behavior electronic data analysis system 76 makes a determination that the machine 20, 66, 68, 70 and 72 is moving 96 then the software of the machine behavior electronic data analysis system 76 may start a vision analytics algorithm that performs an optical flow analysis 98 of the video data stream 86. For example, the video data stream 86 may be a sequence of frames or images of the machine 20 captured over a specified time and the optical flow analysis 98 may analyze the each frame of the video data stream 86 in order to detect any apparent motion that may be observed at a point between each frame.

In some embodiments, the first part of the optical flow analysis 98 may be to determine whether the machine 20, 66, 68, 70 and 72 is swinging 100 the boom 36, arm 38 and/or tool 32. If the optical flow analysis 98 determines that the machine 20, 66, 68, 70 and 72 is not swinging 102 then the optical flow analysis 98 may determine that the machine 20, 66, 68, 70, and 72 has either dumped its load or is picking up a load based on the previous clustered swing state 104. On the other hand, if the optical flow analysis 98 determines the machine 20, 66, 68, 70 and 72 is swinging 106, then the optical flow analysis 98 looks to detect the tool 32 (e.g. bucket) 108. In some embodiments, if the tool 32 is not detected 110, the swing may be determined to be empty 112. However, if it the tool 32 is detected 114, then the swing may be determined to be loaded 116. The exemplary process flow 84 described above may be tailored to a machine behavior data collection system 52 installed on a specific machine type. It will be appreciated that the machine behavior data collection system 52 and the machine behavior data analysis system 76 are compatible with a plurality of different machine types, such as, excavators, backhoes, front-end loaders, bulldozers, dump trucks and other such machines. As such, the process flow 84 may be modified to capture and analyze a plurality of different behaviors of the different machines.

Such an activity and behavior classification system may be configured to be compatible with a wide range of industrial machines such as, excavators, backhoes, front-end loaders, bulldozers, dump trucks and other such machines. Furthermore, the activity and behavior classification system of the present disclosure may be compatible with new machines as well as legacy machines already in use in the field. More specifically, the activity and behavior classification system may be designed such that it may be used on machines that come from different manufacturers. One non-limiting example of a machine classification method using the activity and behavior classification system is described below.

Referring to FIG. 6, an exemplary flowchart is illustrated describing a method 118 which may be followed to monitor and classify the activity and behavior of the machine 20, as described in the present disclosure. The first step 120 of the method 118 may require installing a machine behavior data collection system 52, the machine behavior data collection system 52 having an imaging apparatus 42 that may be mounted on the machine 20, a computer and storage device 54 and a communications apparatus 56. The imaging apparatus 42 may be configured to monitor and capture the actions and movement of the machine 20. In some embodiments, the machine behavior data collection system 52 may additionally be coupled to one or more sensors 44, 46 and 48 mounted on the machine 20.

According to the next step 122 of method 118, a machine behavior electronic data analysis system 76 may be assembled and paired with the machine behavior data collection system 52. Moreover, in some embodiments, the machine behavior electronic data analysis system 76 may be housed in an operations center 50 that is located somewhere on the job site 22 or at an off-site location. Furthermore, the machine behavior electronic data analysis system may have a data analytics module 80 and a communications apparatus 78. In some embodiments, the communications apparatus 78 may allow the machine behavior electronic data analysis system 76 to communicate with the machine 20 and the machine behavior data collection system 52.

In a step 124, machine behavior data 49 may be collected by the imaging apparatus 42 and sensors 44, 46, 48. In one non-limiting embodiment, the machine behavior data 49 collected by the imaging apparatus 42 and sensors 44, 46, 48 may be saved to the computer and storage device 54 of the machine behavior data collection system 52. Additionally, or alternatively, in some embodiments, the communications apparatus 56 of the machine behavior data collection system 52 may transmit the machine behavior data 49 to the communications apparatus 78 of the machine behavior electronic analysis system 76.

The next step 126 of method 118 may provide that the machine behavior data 49 file received by the machine behavior electronic data analysis system 76 is analyzed by the data analytics module 80. In some embodiments, the machine behavior data 49 file may provide an image data file or video data stream 86 of the machine 20 and surrounding job site 22. Moreover, the data analytics module 80 may use object detection and optical flow analysis 98 during the analysis of the data file. Furthermore, according to the final step 128, the object detection and optical flow analysis 98 may be used to recognize various behavior states of the machine 20. In some embodiments, the analysis may be further used to determine a behavior of the machine 20, an operating environment or job site 22 surrounding and a set of actions that are performed by the machine. As a result of the analysis, certain metrics may be determined that may allow for the optimization of machine 20.

It will be appreciated that the detection and monitoring of machine activity is difficult and often requires the use of multiple sensors. Furthermore, it is common practice that a mix of different types of equipment, often from different manufacturers, may be utilized at large job sites. This diversity of the equipment fleet can add to the difficulty of providing a system to monitor machine activity and behavior. As a result, an improved machine behavior analysis and optimization system is needed that is compatible with all pieces of equipment in use at a job site.
